PACKETING-MACHINE.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed February 26, 1910. Serial No. 546,109.

To all whom it may concern Be it known that I, CARL SIGFRID Nrnnno, a subject of the King of Sweden, and resident of 7 Radhusgatan, Siidertelje, in ,the Kingdom of Sweden, engineer, have invented certain new and useful Improvements in Facketing-Machines, of which the following is a specification, reference being made to the accompanying drawings.

The present invention relates to devices in packeting machines having for its purpose to accomplish the folding at the ends of the packet of the paper wrapped around it in the machine and having been folded over one edge at each of its ends, and thereupon to paste the flaps at the ends, and if desired, also to-label the packet.

A machine carried out according to the present invention is shown on the accompanying drawings in which Figure 1 is a front elevation, Fig. 2 an end elevation and Fig. 3 a plan of the machine. Fig. 4 is a detail.

The device for making the first folding of the wrapper at the ends of the packet is assumed to consist of folding plates, jaws or the like, 1, belonging to the packeting machine and which are carried by displaceable rods 2. Between said jaws is shown a square packet 3 (containing for instance matchboxes) over the ends of which the jaws have descended and thereby carried out the said first folding down of the wrapper. The packet 3 is assumed to be in the position in the machine where it has been provided with the wrapper and has been caught between the jaws 1, and from which place one packet after the other is moved forward (to the right in Figs. 1 and 3) by the said jaws toward the devices which form the object of this invention. In Figs. 1 and 2-3 is shown a number of packets thus moved, designated with the numbers 4, 5, 6, 7 and 8, of which the one after the other is acted upon by a device adjacent to each packet either while being moved from one position to another or while at rest in a certain position.

When the rods 2 are displaced in order to move forward the packet 3, the said rods move so far as to cause the packet to assume the position which in the drawing is assumed by packet 4. Above the latter there is a presser foot 9, which, as soon as the packet has assumed the position in which packet 4 lies, descends on and holds fast the latter, whereupon the jaws 1 first ascend straight up and then move back to fetch the next packet. The packet which has been introduced under the presser foot, 9, and which has the wrapper folded only at one place at each end has thus the wrapper project-ing from the side edges 10 and 11 as well as from the under edge 12. While the next packet 3 is being moved forward to the position of packet 4, folders 13, which are adjustably secured to the rods 2 in front of the jaws 1, will strike the wrapper projecting from the said edges 10 of the packet 4, so that the said wrapper will be folded over the said edges. The folders 13, whose front edges are suitably rounded, will then slide up on the ends of the packet 4, until a plate -l which is placed at the back of each folder and extends somewhat into the path of the packets, strikes against the back of the packet, whereupon the latter is moved forward till it assumes the position of packet 5, whereby the latter aS well as all the packets in front of the same are moved by the packet 4 a distance equal to the breadth of a packet in the direction of the movement. In order that the packet 4 may rest securely in its position under the presser foot 9, while the folders 13 slide on its ends, the presser foot is at the front edge provided with a low shoulder 15, against which the upper front edge of the packet rests. WVhile the folders 13 are slidingv on the ends of the packet, the lower ends of the folders are a little above the lower edge of the packet, in order that the wrapper along this edge may not be injured by the folders. As soon, however, as the plates 14 have come against the back of the packet, and the folding over the edges 10 has taken place, the folders 13 descend with their lower ends completely down on the underlying wrapper, whereby the latter is folded sharply at the under edges 12 of the packet. In order that the shoulder 15 may not hinder the packet 4 when it is being moved forward, the resser foot 9 is lifted slightly, as soon as t eforward movement is to begin, The,packet 4 is then first moved forward alone by the plates 14, until it comes against the packet 5, whereupon all thepackets in front of packet 4 are moved forward by the same. The forward movement ceases' when the packet 4 reaches theposition assumed by the packet 5 in the drawing and at this point packet 3 wrapper at the ends of the packet is then folded in the manner shown in packet 5 in Fig. 3. The next folding which is to be done is the folding around the upright edges 11, and it is performed with the aid of folders 17, each of which consists of an angular plate, connected with an arm 18, which at the back is adjustably connected with a pin 19, so that the arm can be adjusted more or less close to the packets. After the adjustment each arm 18 may turn around its pin 19, and this latter is carried by a sleeve 20, which is rotatably mounted on a pin 21, the longitudinal direction of which is at right angles to the longitudinal direction of the pin 19, in consequence of which the folders 17 can move to and from the packet which is between the same as well as up and down. In order to hold the folders 17 against the packet lying between them, each arm 18 is provided with an upright pin 22, which pins are connected by means of a spring 23, which pulls the folders toward one another. \Vhen the acket 5 stops in the position shown in the rawing, its front side is about in a line with the rear sides of the folders 17 so that, when the packet 5 is moved forward by the packet 4 which lies behind it, the wrapper is folded along the upright edges 11.

The folders 17 the upright corners of which are suitably rounded, as shown in Fig.

3, are kept slightly lifted during the time required for the packet to be moved forward to the place assumed on the drawing by packet 6, whereu on the folders descend, so

that a sharp fold is formed at the under edge 12, and the folders have their under sides resting on the flap 24 which the wrapper now forms at each end of the packet. When the next packet 4 pushes forward the packets in front of the same, the packet 6 is pushed forward to the place assumed in the drawing by the packet 7, in which position each of at the lower end of a paste magazine 26, Fig. i

4, and is fixed to a shaft 27, which is provided with a ratchet wheel 28 or the like, a

with which engages a spring 29, a pawl, or the like. The magazines 26, which are movable up and down, descend with their rollers 25 on the flaps 24, as soon as the packet has reached the position assumed in the drawing by packet 7. During the downward movement of the magazines each of the ratchet wheels 28, and thus also the rollers 25 are made to rotate bythe stationary spring 29, and thus the rollers carry on their circumferences paste from the magazines so that when they come in contact with the underlying flaps 24 these will be provided with paste. When the packet 7 then is moved to the position assumed in the drawing by the packet 8, each of the flaps 24 slides up on and is turned up toward and pressed against the end of the packet by a plowshare-shaped plate such as is used for the same purpose in previously known packeting machines.

As to the above named movable parts of the machine, the jaws 1 and the folders 13 are set in motion by parts of the packeting machine which do not belong to this invention. As to the other movable parts, the presser foot 9 is fixed to the end of an upright rod 30, and the presser foot 16 to a similar rod 31. The rod 30 is movable up and down in a sleeve 32, which is firmly united or in one piece with another sleeve 33, in which the rod 31 is movable up and down. The last named sleeve 33 is integral with or forms part of a cross iece 34, which at each end is attached to an carried by an upright rod 35, which is movable longitudinally in the frame of the machine. At the lower ends the rods 35 are connected by means of another cross piece 36, which carries a roller 37, which rests against a cam 38 on the driving shaft 39 of the machine, whereby the rods 35, the cross piece 34 and the sleeves 38 and 33 are set in an up and down motion. This motion is so timed that the presser feet 9 and 16 when required will be lifted by the sleeves 32 and 33 striking against the collars 40 and 41 fixed to the rods 30 and 31. In order to regulate the pressure with which the feet 9 and 16 press against the underlying packets, the rods 30 and 31 are at their upper ends provided each with a cup 42, 43, in which shot or the like can be introduced and removed. The above named up and down motion of the folders 17 is brou ht about by each of the folders being provi ed with a projection 44, which extends in over the presser foot 16 and is there provided with an adjusting screw 45, which has to be the machine frame.

so adjusted that the folder 17 is lifted to the desired height by the presser foot 16. The' required u and down motion of the magazines 26 is rought about by their being carried by arms 46, wlnch pro ect from or are attached to the cross piece EH or the rods In order to prevent the presser feet from turning, there is attached to each rod, 30 and 31, an arm 47, the end of which has the form of a fork 48, in which the other one of the rods 30 and 31 lies.

In order to provide the ready folded packets with the usual labels, one of which is fas tened on that side of the packet where is the end of the wrapper, and one on each end of the packet over the folds of the wrapper, there is in a suitable place above the row of ready folded packets lying on the machine table a paste magazine 49 and on each side of the row a paste magazine 50. These magazines may be arranged in some previously known way so as, when they come in contact with the surface of the packet to be pasted, to supply the same with pa'ste. The paste magazine 49 is carried by an arm 51 extending from the cross piece 34, whereby the magazine is moved by the latter to and from the underlying packet. The two magazines 50, on the other hand, are approached to and removed from the row of packets bymeans of rods 52 of which there is one on each side of the machine table. Each rod 52 carries at a suitable place the magazine which is on its side of the table and is at either end provided with a pin 53, which passes into a corresponding recess in the machine table. so that the rods'52 can be moved to and from the table. The rods 52 are pulled toward the machine table by springs 5% connecting the same, while the device for drawing the. rods apart consists of cam surfaces 55, one of which is at either end of each of the rods and two of which are carried by the rods and the two other by a couple of rods 56, which at their upper ends are connected by means of a cross piece 57, and, like the rods 35, acted upon by the driving'shaft and movable up and down in Against the cam surfaces 55 rest rollers 58, which are fixed to the ends of the rods and pressed by the springs 54 against the cam surfaces, so that, when the rods 35 and 56 move up and down, each rod 52 will move to and from the machine table and thus move the paste magazine 50 fixed to it to and from the opposite packet. In order afterward to fix the labels on the packets where the same have been provided with paste, there is above the row of packets a label magazine 59, which is carried by the cross piece 57 and moved by the rods 56 to and from the underlying packet, whereby the undermost label in the magazine is fixed to the packet. For labeling the ends of the packets, there is fixed on each of the rods 52 a label magazine (30, which on the inward motion of the red fixes a label on the packet opposite the same. The now necessary pressing of the labels is done by brushes or the like, of which one brush ()1 is carried by the cross piece 57 and one brush (32 by each of the rods 52. It is obvious that all these brushes are moved to and from the packets opposite the same.
